This nymph keys pretty well to Neoleptophlebia
. Under the microscope, the fork on the first gill is more symmetrical than it looks in the picture here. Following the species key in Jacobus et al. (2014)
, the lack of tusks on the head or postero-lateral
spines on segment 8 leads to adoptiva
, but both refer to a 3-segmented labial palp
as a key characteristic, and this one only seems to have two segments, just like another, different-looking specimen
from the same sample. So I'm stuck.
I thought the end of the abdomen
of this one was damaged during capture and transport, but I photographed it anyway because it looked different from the others. However, it became clear under the microscope that it was actually just mid-way through molting and the abdomen
was intact underneath. I got a couple nice microscope photos showing that. The pattern of markings on the abdomen
is still distinctive compared to the other specimen, which was more representative of a common nymph in my sample. This one was unique.
